⚫️Hibbard Inshore recently completed a 22.7km inspection of the Tala Hydropower Plant headrace tunnel and a 6.5km inspection of the Chhukha Hydropower Plant headrace tunnel with our Saab Sabertooth AUV/ROV system for Druk Green Power in Bhutan. The Sabertooth provided 3D multibeam profiling, and forward-looking imaging sonar data in both tunnels.
⚫️During the longer Sabertooth inspections our smaller LBV ROV system provided underwater video of the penstocks, desilting chambers, surge shafts, gates and their guides.
⚫️The primary objective of this inspection was to provide data on the current conditions of each structure and look for any signs of damage, sedimentation, or liner damage. The data collected from this inspection will be utilized to determine the current condition and whether maintenance or remediation tasks would need to be performed as a result of the findings.
⚫️In 2011, Hibbard Inshore inspected the headrace tunnel of Chhukha, including its intake structures, desilting chambers, head race tunnel, surge shaft, pressure shaft and penstocks. During the same year, the Hibbard inspected the Tala surge shaft and found two holes at the bottom of surge shaft, which we were able to provide an ROV option for plugging. (Link?)
⚫️The Chhukha Hydropower Plant has an installed capacity of 336 MW and was commissioned between 1986 to 1988 while Tala Hydropower Plant has an installed capacity of 1020MW and was commissioned between July 2007 to March 2008.
⚫️Hibbard Inshore is proud to work with our partner Druk Green Power in providing inspections for their Hydropower Plants, and look forward to the continued use of their water conducting systems in the future!
